Linking to the scenario, a cars motor gets
very hot and is very important to know that heat is dispersed through the engine.
If you have poor heat management, it can lead to engine failure and could
explode. This is why specific heat capacity is vital when designing and
building engines and large machinery.
Water has a high specific heat capacity, and
is very effective when acting as a cooling agent in engines. water has a high
specific water due to presence of
intermolecular hydrogen bonding in it The amount of heat supplied is used
initially to break the bonding reason water has high specific heat capacity. A
large amount of heat is used to break the hydrogen bonds rather than increasing
the water’s movement energy
water pump flows the water around the engine, and the heat produced by the
engine is absorbed by the water. That hot water that circulates around the
engine walls is then forced into the cars radiator where the heat from the
water is released through the cooling fan. Engine parts constantly expand and
contract due to the fluctuation in heat within the engine. That is why it’s
important to put metals with similar specific heat capacities are put together,
because if one metal heats up faster than the other and they’re connected, and
one expands faster than the other, then cracking and splitting may occur.
Materials that have lower specific heat capacities are prone to gaining more
heat, or heat up quicker even if a smaller amount of heat energy is applied to
that material. These materials are very useful for cooking appliances. Despite
the fact that the heating element of a kettle has a low specific heat capacity,
the outer casing of kettle would have to have a higher specific heat capacity
so that you don’t burn your hand.
In a cooking pot, it would generally have a
copper base, which has low specific heat capacity to absorb the heat. It’s also
very stable so that the pot, it would generally have a copper base
In a cooking
pot, it would generally have a copper base, which has low specific heat
capacity to absorb the heat. It’s also very stable. Also, wood is often used as
the handles of the put due to woods low conductivity of heat.
temperature the liquid and the material that is in the thermometer must
have low specific capacities for accurate measurements of the temperature.
The thermometer which has a specific heat capacity of 0.84 J/g and the mercury
which is the liquid in thermometers have a specific heat capacity of 0.14 J/g.Thisis
why mercury is used in thermometers.
